I have always been skeptical of the hevi-shot claims, but I'm now a believer. As I posted earlier, I purchased a HS Strut Undertaker turkey tube for the TDC 20 gauge and I was waiting on my order of Hevi 13 turkey loads. The load is HEVI 13, HEVI-SHOT, 20 gauge, 3", 1.25oz. Shot, 1090 FPS, shot size #6. This gun went from putting fewer than 5 pellets in the kill zone at 30 yards to putting an average of 14 pellets in the kill zone at 30 yards. One shot even put 21 hits in the brain and spine areas of the turkey target I was using. I didn't pattern it at any other distances and will probably not shoot over the 30 yard mark when hunting, but I may try a few at a target at 40 yards just to see how it performs. Needless to say, I believe Hevi-shot is worth the extra money. For this particular set up any way.
